Illustrates mig welding techniques. Shows how the spray arc and short arc work, how to set up the equipment and adjust the shielding gas, welding wire, welding current, and torch in preparation for welding Topics: Electric welding, Electric welding
An introduction to the Heliarc (TIG) welding process. Includes an animated diagram of a TIG torch, showing how the welding current, shielding gas, and cooling water flow through the torch. Covers setting up the torch and electrode, checking gas, water and electrical connections, and setting welding current and shielding gas pressure Topics: Electric welding, Welding, Electric welding, Welding

Created in 1954 by General Electric, "The Atom Goes To Sea" shows the peaceful use of the atom -- used in a nuclear reactor to create power. Ironically, the initial use of this reactor will be aboard a ship of war -- the submarine USS Nautilus (completed in 1955). This film explains how an atomic powered submarine operates and contains scenes at the National Reactor Test Site in Arco, Idaho, the Knolls Atomic Power Laboratory in Schenectady and the submarine reactor test site at...

Reel 1 shows rain storms and flooded streams, the flooded Tennessee River valley, Norris Dam and Wilson Dam, and a panorama of eroded land. Phosphate fertilizer is made in an electric furnace at Muscle Shoals, is bagged, and is shipped to the farmer. Contrasts productivity of fertilized and non-fertilized land. Reel 2 shows crops and cattle on a farm, a delegation of farmers conferring with a county agent, the power house at Wilson Dam, electric power lines and towers, a reservoir, and a...

This film in the "Magic of the Atom" series was produced in 1964 by the Handel Film Corporation. "Atomic Power Production" explains how heat is created by the controlled chain reaction of atomic fuel in a reactor is converted to electrical power. The basic differences in these power reactors are discussed: the boiling-water reactor, the pressurized-water reactor, and liquid-metal-cooled reactor, and the organic-cooled reactor. The principal of the breeder reactor is... Topics: Electric Generation, Nuclear Reactor, Nuclear Power, Fossil Fuel, Uranium, Enrico Fermi Nuclear...
This 1962 film about the Big Rock Point Nuclear Power Plant features Hollywood actor Ronald Reagan -- who often worked for General Electric in this era -- as its narrator. The film was shown at the plant's visitor's center for many years, touting the benefits of atomic fission and showing the inner workings of the power plant. Workers are shown looking down into the reactor where a lead covered "head" shields them from radioactivity. Beneath this head are 56 fuel bundles, containing...
